メンバ	解説
ActivateOnly	アクティブ化のみ。オブジェクトは選択 (コピーおよび貼り付け用) できますが、編集はできません。
AllowEdit	編集可能。グリッドがオブジェクトの内容の編集を試みます。
Disabled	禁止。オブジェクトはアクティブ化できず、テキストの選択や編集もできません。
NoEdit	編集不可。オブジェクトをアクティブ化 (テキストをハイライト表示) できますが、セルの編集または選択 (コピーや貼り付け) はできません。

解説

この列挙体は、UltraGridColumn の UltraGridColumn.CellActivation、UltraGridRow の UltraGridRow.Activation および UltraGridCell の UltraGridCell.Activation プロパティを指定するために使用されます。
